Question:
An optical fiber is characterized by
An optical fiber is characterized by
Show Hint
TIR is essential for light propagation in optical fibers—core must have higher refractive index than cladding.
Updated On: May 26, 2025
- Total internal reflection
- A core material of reflective index lower than that of cladding
- Scattering loss
- Diffraction
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Optical fibers operate on the principle of total internal reflection (TIR). Light is guided through the core of the fiber by repeatedly reflecting off the core-cladding boundary, which requires the core to have a higher refractive index than the cladding.
